LONDON, England (CNN) -- Aircraft manufacturer Airbus is ready to fund a third search of the Atlantic Ocean if a second search, now under way, fails to find debris from last month's Air France crash, the company said Friday.

Investigators pore over wreckage of Air France flight 447 which crashed killing 228 people on June 1.

Airbus is discussing a payment of between 12 to 20 million euros ($17-28 million) to help pay for a third search, but it is still too early to settle on a figure, company spokesman Stefan Schaffrath said.

"We are ready to give a significant share, whatever is needed," he told CNN.

The company is driven by the desire to understand what caused the crash of Air France Flight 447 on June 1, he said. All 228 people aboard were killed.

"Our priority is increasing aviation safety," Schaffrath said. "The aviation community can learn from an accident."

Airbus is already helping in the second search alongside Air France and the French accident investigations agency, the BEA.
